MTT assay of (A) biocompatibility of blank DNA-NWs and (B) cytotoxicity of CPT-loaded DNA-NWs compared with equivalent concentrations of free CPT solution. (C) Flow cytometry assessment of the biocompatibility of blank solution, DNA-NW solution, and the cytotoxicity of CPT-loaded DNA-NW.
Fig. 7.
Surface binding of DNA-NW loaded with FITC-tagged CPT to the human liver cancer cell line (HepG2) compared with the control cell line (CHSE-214) derived from the salmon embryo after a 30 min interval. (A) As HepG2 cells are rich in scavenger receptors, DNA-NW binds the cell surfaces followed by gradual internalization into the cells and release of FITC-tagged CPT into the cytoplasm. (B) As CHSE-214 cells lack scavenger receptors, DNA-NW could not bind these cells effectively, resulting in inferior cell internalization.
